0499e53fe5 New command line parsing. This isn't as perfect as I would have liked. The CommandLine Library needs to be extended, in order to parse the options and allow for optional dashes. In addition, the help option isn't correct since I do the parsing mostly myself. But this is in the ocorrect ar format.

f3373f7bc9 Make assertion stricter. Since the source operands are allocated at 
this point, the second operand must be a physical register (it cannot
be a virtual one).

a2ac517a20 Emit & read more compressed bytecode by not emitting a bytecodeblock for 
each basic block in function.  Instead, just emit a stream of instructions,
chopping up basic blocks based on when we find terminator instructions.  This
saves a fairly substantial chunk of bytecode space.  In stripped, sample
cases, for example, we get this reduction in size:

197.parser: 163036 -> 137180:  18.8% reduction
254.gap   : 844936 -> 689392:  22.6%
255.vortex: 621724 -> 528444:  17.7%

...

Not bad for something this simple.  :)  Note that this doesn't require a new
bytecode version number at all, though version 1.1 should not need to support
the old format.

e9269b7cc5 Add an option to enable the SSA based peephole optimizer. 
Eventually this pass will provide substantially better code in the interim between when we
have a crappy isel and nice isel.  Unfortunately doing so requires fixing the backend to
actually SUPPORT all of the fancy addressing modes that we now generate, and writing a DCE
pass for machine code.  Each of these is a fairly substantial job, so this will remain disabled
for the immediate future.  :(

6f1c35bc68 Add a new SSA-based peephole optimizer which includes copy propagation and 
folding of instructions into addressing modes.  This creates lots of dead
instructions, which are currently not deleted.  It also creates a lot of
instructions that the X86 backend currently cannot handle.  :(

c1409f46b6 Print instructions before register allocation is performed. Also fix 
bug where spill instructions were added to the next basic block
instead of the end of the current one if the instruction that required
the spill was the last in the block.

acb0d474e9 Go back to allocating memory for each constant separately. Since SPARCs do not 
allow unaligned loads, that is probably the problem I've been seeing in numerous
SPARC test cases failing. X86, on the other hand, just slows down unaligned
accesses, since it must make 2 aligned accesses for each unaligned one.
